A mathematical model can be used to predict important properties of a device, based on its geometry, tabulated material properties, and the equations describing relevant physics. We do standalone modeling and analysis projects, and also use modeling frequently in our design process.

The first and simplest tool for a physics model is a pencil and paper, which is usually sufficient. Another quick modeling tool is SolidWorks with built in simulation functions that are useful for finding stress concentrations and deflection of the part.

For finite element modeling of structural, electrical, thermal, and fluidic systems, or for full-custom equation-based PDE modeling, we typically use COMSOL Multiphysics. We use the SolidWorks livelink and the Optimization module, which we use to perform overnight nonlinear constrained optimization on part geometries.

 

We also use a number of domain-specific tools. We frequently use ANSYS Mechanical to calculate normal modes in aerospace parts, check for engineering margins, and to optimize the parts for weight. For printed circuits, we use POLAR to design stackups and calculate trace specifications. For radiation physics, we use GEANT4 from CERN. Finally, for full-custom from-scratch physical modeling, we typically use MATLAB.
